RULES OF BASKETBALL

The rules of basketball are the rules and regulations that govern the play, officiating,

equipment and procedures of basketball. Most leagues, including the National

Basketball Association, govern their own rules. In addition, the Technical Commission

of the International Basketball Federation (FIBA) determines rules for international

play.

Original Rules

James Naismith published in 1891, his rules for the game of "Basket Ball" that he

invented:

[1]

The original game played under these rules was quite different than the one

played today as there was no dribbling, dunking, or three pointers.

1. The ball may be thrown in any direction with one or both hands.

2. The ball may be batted in any direction with one or both hands.

3. A player cannot run with the ball. The player must throw it from the spot on

which he catches it, allowance to be made for a man who catches the ball when

running at a good speed if he tries to stop.

4. The ball must be held in or between the hands; the arms or body must not be

used for holding it.

5. No shouldering, holding, striking, pushing, or tripping in any way of an opponent.

The first infringement of this rule by any person shall count as a foul; the second

shall disqualify him until the next basket is made or, if there was evident intent to

injure the person, for the whole of the game. No substitution shall be allowed.

6. A foul is striking at the ball with the fist, violation of rules three and four and

such described in rule five

7. If either side makes three consecutive fouls, it shall count a goal for the

opponents (consecutive means without the opponents in the mean time making a

foul).

8. A goal shall be made when the ball is thrown or batted from the grounds into the

basket and stays there (without falling), providing those defending the goal do

not touch or disturb the goal. If the ball rests on the edges, and the opponent

moves the basket, it shall count as a goal.

9. When the ball goes out of bounds, it shall be thrown into the field of play and

played by the first person touching it. In case of dispute the umpire shall throw it

straight into the field. The thrower-in is allowed five seconds. If he holds it

longer, it shall go to the opponent. If any side persists in delaying the game, the

umpire shall call a foul on that side.

10. The umpire shall be the judge of the men and shall note the fouls and notify the

referee when three consecutive fouls have been made. He shall have power to

disqualify people according to Rule 5.

11. The referee shall be judge of the ball and shall decide when the ball is in play, in

bounds, to which side it belongs, and shall keep the time. He shall decide when a

goal has been made and keep account of the baskets, with any other duties that

are usually performed by a scorekeeper.

12. The time shall be two fifteen-minute halves, with five minutes rest between.

13. The side making the most points in that time is declared the winner.

Players, substitutes, teams and teammates

Naismith's original rules did not specify how many players were to be on the court. In

1900, five players became standard, and players that were substituted were not allowed

to re-enter the game. Players were allowed to re-enter a game once from 1921, and

twice from 1934; such restrictions on substitutions were abolished in 1945 when

substitutions became unlimited. Coaching was originally prohibited during the game,

but from 1949, coaches were allowed to address players during a time-out.

Originally a player was disqualified on his second foul. This limit became four fouls in

1911 and five fouls in 1945, still the case in most forms of basketball where the normal

length of the game (before any overtime periods) is 40 minutes. When the normal

length is 48 minutes (this is the case with the National Basketball Association in the

United States and the National Basketball League in Australia, among others) a player

is accordingly disqualified on his sixth foul.

Shot clock and time limits

See also: Defensive three-second violation

The first time restriction on possession of the ball was introduced in 1933, where teams

were required to advance the ball over the center line within ten seconds of gaining

possession. This rule remained until 2000, when FIBA reduced the requirement to eight

seconds, the NBA following suit in 2001. The NCAA retains the 10-second rule for

men's play, but has never adopted a time limit for women's play. U.S. high schools,

whose rules are drafted by NFHS, also use the 10-second rule for both sexes.

In 1936 the three-second rule was introduced. This rule prohibits offensive players

from remaining near their opponents' basket for longer than three seconds (the precise

restricted area is also known as the lane or the key). A game central to this rule's

introduction was that between the University of Kentucky and New York University.

Kentucky coach Adolph Rupp did not take one of his referees with him, despite being

warned of discrepancies in officiating between the midwest and east by Notre Dame

coach George Keogan, and the game became especially rough. Because of this game

and others, 6'5" (1.96 m) Kentucky All American center Leroy Edwards is generally

recognized as the player responsible for the 3 second rule.

While the rule was originally adopted to reduce roughness in the area between big men,

it is now considered to prevent tall offensive players from gaining an advantage by

waiting close to the basket. When the NBA started to allow zone defense in 2001, a

three-second rule for defensive players was also introduced.

The shot clock was first introduced by the NBA in 1954, to increase the speed of play.

Teams were then required to attempt a shot within 24 seconds of gaining possession,

and the shot clock would be reset when the ball touched the basket's rim or the

backboard, or the opponents gained possession. FIBA adopted a 30-second shot clock

two years later, resetting the clock when a shot was attempted. Women's basketball

adopted a 30-second clock in 1971. The NCAA adopted a 45-second shot clock for

men while continuing with the 30-second clock for women in 1985. The men's shot

clock was then reduced to 35 seconds in 1993. FIBA reduced the shot clock to 24

seconds in 2000, and changed the clock's resetting to when the ball touched the rim of

the basket. Originally, a missed shot where the shot clock expired while the ball is in

the air constituted a violation. In 2003 the rule was changed so that the ball remains live

in this situation, as long as it touched the rim. If the ball touches the rim and slightly

bounces over the basketball hoop it will be called as a loose ball.

Fouls, free throws and violations

Dribbling was not part of the original game, but was introduced in 1901. At the time, a

player could only bounce the ball once, and could not shoot after he had dribbled. The

definition of dribbling became the "continuous passage of the ball" in 1909, allowing

more than one bounce, and a player who had dribbled was then allowed to shoot.

Running with the ball ceased to be considered a foul in 1922, and became a violation,

meaning that the only penalty was loss of possession. Striking the ball with the fist has

also become a violation. From 1931, if a closely guarded player withheld the ball from

play for five seconds, play was stopped and resumed with a jump ball; such a situation

has since become a violation by the ball-carrier. Goaltending became a violation in

1944, and offensive goaltending in 1958.

Free throws were introduced shortly after basketball was invented. In 1895, the free

throw line was officially placed fifteen feet (4.6 m) from the backboard, prior to which

most gymnasiums placed one twenty feet (6.1 m) from the backboard. From 1924,

players that received a foul were required to shoot their own free throws. One free

throw shot is awarded to a player who was fouled while making a successful field goal

attempt. If the field goal attempt is unsuccessful, two free throw shots are awarded

(three if the player was attempting a three-point field goal). If an offensive player is

fouled while not in the act of shooting, or if a player is fouled in a loose-ball situation,

the penalty varies by level of play and the number of fouls accumulated by the

opposing team in a given period.



o

In NCAA and NFHS play:

If the player's team has 6 or fewer team fouls in the half, the team fouled

gets possession of the ball.

o

If the team has 7 to 9 team fouls, the player fouled goes to the line for

what is called "one-and-one" or the "bonus"—that is, if the player makes the first

free throw, he gets the opportunity to attempt a second, but if he misses, the ball

is live.

o

If the team has 10 or more fouls in the half, the player fouled gets two free

throws, often called the "double bonus".

o

All overtime periods are considered an extension of the second half for

purposes of accumulated fouls. Also, NFHS rules accumulate fouls per half,

even though games are played in quarters.



o

In the NBA:

If the player's team has 4 or fewer team fouls in the quarter, the team

fouled gets possession of the ball.

o

Starting with the team's fifth foul in the quarter, the player fouled gets two

free throws.

o

Overtime is not considered an extension of any quarter. Instead, the

"penalty" of two free throws is triggered on the team's fourth foul in that

overtime period (instead of the fifth).

o

Foul limits are reset in the last two minutes of a quarter or overtime period.

If a team has not reached its limit of accumulated fouls, the first team foul in the

last two minutes results in possession by the team fouled, and all subsequent

fouls result in two free throws.



o

In FIBA play:

If the player's team has 4 or fewer team fouls in the quarter, the team

fouled gets possession of the ball.

o

Starting with the team's fifth foul in the quarter, the player fouled gets two

free throws.

o

During an interval of play, all team members entitled to play are

considered as players.

o

The ball become dead when an official blows his whistle while the ball is

live

A player has 10 seconds to attempt a free throw. If the player does not attempt a free

throw within 10 seconds of receiving the ball, the free throw attempt is lost, and a free

throw violation is called. A free throw violation also occurs if a free throw misses the

backboard, rim, and basket, and rim. If a free throw violation is assessed in the last free

throw awarded to a player in a given situation, possession automatically reverts to the

opposing team.

A charge is physical contact between an offensive player and a defensive player. In

order to draw an offensive charge the defensive player must establish legal guarding

positioning in the path of the offensive player. If contact is made, the officials would

issue an offensive charge. No points will be allowed and the ball is turned over. The

defensive player may not draw an offensive charge in the "restricted zone" (see below

for more details).

[2]

Blocking is physical contact between the offensive player and the defensive player.

Blocking fouls are issued when a defensive player interferes with the path of the

offensive player in the shooting motion. Blocking fouls are easily called when the

defensive player is standing in the "restricted zone".

[2]

Restricted zone: In 1997, the NBA introduced an arc of a 4-foot (1.22 m) radius around

the basket, in which an offensive foul for charging could not be assessed. This was to

prevent defensive players from attempting to draw an offensive foul on their opponents

by standing underneath the basket. FIBA adopted this arc with a 1.25 m (4 ft 1.2 in)

radius in 2010.

[3]

Equipment

The goal is placed 10 feet (3.05m) above the court. Originally a basket was used (thus

"basket-ball"), so the ball had to be retrieved after each made shot. Today an

open-bottom hoop is used instead.

Officiating and procedures

Main article: Official (basketball)

Originally, there was one umpire to judge fouls and one referee to judge the ball; the

tradition of calling one official the "referee" and the other one or two the "umpires" has

remained (the NBA, however, uses different terminology, referring to the lead official

as "crew chief" and the others as "referees"). Today, both classes of officials have equal

rights to control all aspects of the game. The NBA added a third official in 1988, and

FIBA did so afterward, using it for the first time in international competition in 2006.

The use of video evidence to inform referee's decisions has always been banned, except

in the case of determining whether or not the last shot of a period was attempted before

time expired. This exception was introduced by the NBA in 2002 and adopted by FIBA

in 2006. The NCAA, however, has permitted instant replay for timing, the value of a

field goal (two or three points), shot clock violations, and for purposes of disqualifying

players because of unsportsmanlike conduct. The NBA changed its rules starting in

2007 to allow officials the ability to view instant replay with plays involving flagrant

fouls, similar to the NCAA. In Italy's Lega A, an American football-style coach's

challenge is permitted to challenge (at the next dead ball) an official's call on any

situation similar to the NCAA.

The center jump ball that was used to restart a game after every successful field goal

was eliminated in 1938, in favor of the ball being given to the non-scoring team from

behind the end line where the goal was scored, in order to make play more continuous.

The jump ball was still used to start the game and every period, and to restart the game

after a held ball. However, the NBA stopped using the jump ball to start the second

through fourth quarters in 1975, instead using a quarter-possession system where the

loser of the jump ball takes the ball from the other end to start the second and third

periods, while the winner of that jump ball takes the ball to start the fourth period from

the other end of the court.

In 1981, the NCAA adopted the alternating possession system for all jump ball

situations except the beginning of the game, and in 2003, FIBA adopted a similar rule,

except for the start of the third period and overtime. In 2004, the rule was changed in

FIBA that the arrow applies for all situations after the opening tap.

In 1976, the NBA introduced a rule to allow teams to advance the ball to the center line

following any legal time-out in the final two minutes of the game. FIBA followed suit

in 2006.

International Rules of Basketball

The most recent international rules of basketball were approved April 26, 2008 by

FIBA and became effective October 1 of that year.

[4]

There are eight rules encompassing 50 articles, covering equipment and facilities,

regulations regarding teams, players, captains and coaches, playing regulations,

violations, fouls and their penalties, special situations, and the officials and table

officials. The rules also cover officials' signals, the scoresheet, protest procedure,

classification of teams and television time-outs.
